JERUSALEM (Reuters) - Israel approved on Tuesday the construction of 1,100 homes for Jews on annexed land in the West Bank, a move that will complicate international efforts to renew peace talks and defuse a crisis over a Palestinian statehood bid at the United Nations. Palestinian President Mahmoud Abbas applied at the UN on Friday for full Palestinian membership, a step opposed by Israel and the United States, which urged him to resume peace negotiations. The so-called Quartet of international mediators the United States, the European Union, Russia and the UN has called for talks to begin within a month and urged both sides not to take unilateral actions that could block peacemaking. Richard Miron, spokesman for UN Middle East envoy Robert Serry, called the decision very concerning. He said settlement activity undermines the prospect of resuming negotiations and reaching a two-state solution to the conflict.
